This paper proposes that polluted water resources, increasing water shortage and inadequate science,technology and education are restrictive factors for sustainable development of the agricultural environment in Dongchnagfu County.The principles of eco-agriculture provide powerful means to abate damage to and sustain agricultural and environmental systems.These principles are to adjust measures to local conditions, to establish a cyclical and regenerative economy and to recognise the economic,social and ecological benefits of change. Elements of ecoagricultural construction include reforming farmland environments,water-farmland-forest relationships, farmland fertility and farmland structure. These changes are considered with development models for greenhouse/climate change actions,methane generation, planting and stock breeding, tourism, market vegetable farming and edible mushroom production.
